1. 7.5 Solve Special Types of Linear Systems You will identify systems that have no solutions and systems that have infinitely many solutions.
Essential Question: How can you identify the number of solutions in a linear system?
3. Independent Practice Check Textbook p. 447-450
4. Independent Practice Check Textbook p. 454-457
5. Vocabulary Exactly One Solution = Consistent and Independent
Graphing – Intersecting Lines
Substitution – Produces a Solution
Elimination – Produces a Solution
Infinite Solutions = Consistent and Dependent
Graphing – Same Line
Substitution – Variables all disappear – Left with True Sentence
Elimination – Variables all disappear – Left with True Sentence
No solutions = Inconsistent
Graphing - Parallel Lines
Substitution – Variables all disappear – Left with False Sentence
Elimination – Variables all disappear – Left with False Sentence
